CFA Level 1 Economics: Complete Study Guide (2026)

All 8 Learning Modules at a Glance

LM 1: The Firm and Market Structures

This is classic microeconomics repackaged for investment analysts. The module opens with profit maximization theory — the rule that maximum profit occurs where marginal revenue equals marginal cost (MR = MC), provided MC is rising — then moves through breakeven analysis, shutdown decisions, and economies of scale before surveying the four market structures.

Breakeven, Shutdown, and Economies of Scale

Breakeven occurs where total revenue equals total cost, or equivalently, where price equals average total cost (ATC). Shutdown happens when price falls below minimum average variable cost (AVC) — at that point, the firm loses less money by ceasing operations than by continuing to produce. This distinction between breakeven and shutdown is tested frequently.

Economies of scale occur when long-run average cost decreases as output increases (think bulk purchasing, specialized equipment, labor specialization). Diseconomies of scale kick in at higher output levels — usually due to coordination complexity, bureaucracy, and communication breakdowns. The long-run average total cost curve is U-shaped for this reason.

The Four Market Structures

For monopolistic competition, firms have some pricing power thanks to product differentiation, but low barriers to entry drive economic profit to zero in the long run as new competitors enter. Demand curves are downward-sloping but relatively elastic.

For oligopoly, the curriculum covers three key models. The Cournot model assumes firms compete on quantity with simultaneous decisions. The Nash equilibrium is the outcome where no firm can improve its payoff by unilaterally changing strategy. The kinked demand curve model explains price rigidity in oligopolies — firms match price cuts (elastic response below the kink) but don’t follow price increases (inelastic response above the kink).

The module finishes with practical tools for determining market structure: concentration ratios (market share of top N firms) and the Herfindahl-Hirschman Index (HHI). Know the limitations of these measures — they don’t capture contestability, potential competition, or geographic segmentation.

LM 2: Understanding Business Cycles

This module covers the four phases of the business cycle, leading/lagging/coincident indicators, credit cycles, and the practical use of economic data for investment decisions.

The four phases: expansion (rising GDP, falling unemployment, increasing confidence), peak (maximum output, capacity constraints appear), contraction (falling GDP, rising unemployment, declining confidence), and trough (minimum output, conditions for recovery begin). The interplay between business cycles and credit cycles is an important CFA concept — credit expansion fuels booms, credit contraction deepens recessions, and the credit cycle often leads the business cycle.

Economic Indicators

The curriculum also covers newer approaches: the use of big data in economic indicators (satellite imagery, credit card transaction data, web traffic), nowcasting (real-time GDP estimation), and the Atlanta Fed’s GDPNow model. These are tested at a conceptual level.

LM 3: Fiscal Policy

Fiscal policy covers government spending and taxation as tools for influencing the economy. The curriculum starts with the roles and objectives of fiscal policy, then moves to deficits, national debt, specific fiscal tools, and the challenges of implementation.

The fiscal multiplier is a key concept: when the government increases spending by $1, total GDP increases by more than $1 because that spending becomes someone else’s income, part of which is spent again. The multiplier is larger when the marginal propensity to consume is higher and when the economy has slack capacity. The balanced budget multiplier — where a simultaneous increase in taxes and spending of equal size still increases GDP — is a classic exam question.

Challenges of fiscal policy: implementation lags (recognition lag, legislative lag, execution lag), political constraints, crowding out (government borrowing pushes up interest rates, reducing private investment), and the difficulty of measuring the fiscal stance — whether policy is truly expansionary or contractionary after adjusting for automatic stabilizers.

LM 4: Monetary Policy

This is the highest-priority macro module. It covers central bank operations, objectives, tools, and the interaction between monetary and fiscal policy.

Central Bank Tools

Open market operations: the central bank buys or sells government securities to expand or contract the money supply. Buying securities injects reserves (expansionary); selling drains them (contractionary). The policy rate: the target interest rate at which banks lend to each other overnight — the Fed funds rate in the US, the main refinancing rate for the ECB. Reserve requirements: the minimum reserves banks must hold against deposits; lowering them frees up lending capacity.

The Transmission Mechanism

How does a policy rate change affect the real economy? The curriculum traces the chain: policy rate change → short-term market rates → bank lending rates → asset prices and exchange rates → spending, investment, and net exports → aggregate demand → output and inflation. Understanding this chain is critical because it explains why monetary policy works with a lag and why different channels can transmit at different speeds.

Inflation targeting is the dominant framework for modern central banks. The curriculum covers the key prerequisites: central bank independence (from political pressure), credibility (markets trust the commitment), and transparency (clear communication of objectives and decisions). Real-world examples include the Bank of Japan’s experience with deflation and the US Federal Reserve System’s dual mandate (price stability and maximum employment).

Exchange rate targeting is an alternative framework where the central bank pegs the domestic currency to another currency or basket. This provides price stability but sacrifices independent monetary policy — a tradeoff known as the monetary policy trilemma (you can only have two of: free capital flows, fixed exchange rate, independent monetary policy).

LM 5: Introduction to Geopolitics

A broader, more conceptual module. It covers state and non-state actors, features of political cooperation and non-cooperation, globalization forces and threats of rollback, international organizations (IMF, World Bank, WTO), geopolitical risk assessment, and the tools of geopolitics (trade agreements, sanctions, military alliances).

The curriculum introduces archetypes of country behavior (autarkic, hegemonic, multilateral) and a framework for assessing geopolitical risk in the investment process: identify the type of risk, assess the threat, estimate the impact, track signposts for escalation or de-escalation, and act on the analysis.

For the exam, this is tested at a conceptual level. Don’t memorize every detail — understand the role of international organizations, the main types of geopolitical risk (event-driven, exogenous, thematic), and how geopolitical factors create investment risk. Budget your study time accordingly.

LM 6: International Trade

Comparative advantage, trade barriers, and regional trading blocs. The key insight: trade based on comparative advantage increases total output — even if one country has an absolute advantage in producing everything. This is the theoretical justification for free trade.

Trade restrictions: Tariffs raise the domestic price of imported goods, benefiting domestic producers and generating government revenue, but harming consumers and creating deadweight loss (reduced total economic welfare). Quotas restrict the quantity of imports directly — the welfare effect is similar to tariffs except the “revenue” goes to whoever holds the import licenses rather than the government. Export subsidies help domestic producers compete abroad but distort markets and invite retaliation.

Trading blocs: The curriculum distinguishes free trade areas (tariffs eliminated among members, each sets own external tariffs), customs unions (common external tariff), common markets (free movement of labor and capital too), and economic unions (harmonized economic policies). Know the spectrum from least to most integrated.

LM 7: Capital Flows and the FX Market

This module bridges macro theory and currency markets. It covers the foreign exchange market structure, exchange rate quotations, currency regimes, and how capital flows interact with exchange rates and trade balances.

FX market basics: The FX market is the world’s largest financial market by daily volume. Key participants include commercial banks (the largest), central banks, corporations, real money investors, and leveraged funds. Trades settle T+2 for most currency pairs.

Exchange rate quotations: Direct quotes express the domestic currency price of one unit of foreign currency (e.g., 1.10 USD/EUR for a US investor). Indirect quotes are the inverse. The curriculum covers bid-ask spreads in FX and the convention that the base currency is the denominator in European terms.

Currency regimes: The taxonomy ranges from no separate legal tender (dollarization, currency board) through fixed pegs, crawling pegs, managed floats, to independently floating. Know the tradeoffs: fixed regimes sacrifice monetary policy independence but provide exchange rate stability; floating regimes allow independent monetary policy but introduce exchange rate volatility.

The module also covers the relationship between exchange rates and the trade balance — how currency depreciation can improve a trade deficit (via the J-curve effect, where the trade balance initially worsens before improving as volumes adjust) and the role of capital restrictions in controlling flows.

LM 8: Exchange Rate Calculations

This is pure computation — and reliable exam points if you drill it. The module covers cross-rate calculations, forward rate calculations, arbitrage relationships, and forward premiums and discounts.

Cross Rates

When you have USD/EUR and USD/GBP, you can derive EUR/GBP by dividing. The key is keeping track of which currency is in the numerator and denominator. Practice cross-rate triangles until the mechanics are automatic.

Forward Rates and Interest Rate Parity

If the price currency has a higher interest rate than the base currency, the forward rate will be higher than the spot rate — the price currency trades at a forward discount (it’s expected to depreciate). This is the no-arbitrage condition that links interest rate differentials to forward exchange rates.

Forward premium or discount: Calculated as (F − S) / S, annualized if needed. A positive value means the base currency trades at a forward premium (the market expects it to appreciate). This connects directly to derivative pricing concepts (currency forwards) and to the time value of money framework.

Arbitrage relationships: If covered interest rate parity doesn’t hold, a riskless profit opportunity exists. In practice, arbitrage activity by market participants quickly eliminates any mispricing, keeping the relationship tight. The exam will present scenarios where you need to identify whether an arbitrage opportunity exists and calculate the profit.

Study Strategy for Economics

Don’t try to master every micro detail — focus on the market structures (LM 1) that are most testable, and spend the bulk of your time on monetary policy (LM 4), capital flows (LM 7), and FX calculations (LM 8). These three modules account for the majority of Economics questions on the exam.

Geopolitics (LM 5) is the lowest priority — understand the framework, know the major organizations, but don’t try to memorize every archetype. Fiscal policy (LM 3) and international trade (LM 6) fall in the middle: know the core concepts (multiplier, tariff effects, comparative advantage) and move on.

The full time allocation is in the study plan — Economics gets Weeks 3–4, roughly 24 hours total.
